In a nonaqueous electrolyte secondary battery including a positive electrode (11) whose surface has a positive electrode mixture layer containing a mixture of a conductive carbon material and a positive electrode active material containing a lithium-containing transition metal composite oxide having a layer structure and represented by the general formula Li a Ni x M (1-x) O 2 (where M represents one or more kinds of elements, and a and x satisfy the conditions 0<a‰¤1.2 and 0.4‰¤x‰¤1, respectively), the proportion of carbon atoms relative to the total atoms on the surface of the positive electrode is made to be not less than 80%. |
